摘　　要：提出了一种基于WSRF的网格资源发现模型,该模型采用三层架构以及集中式与分布式相结合的资源组织结构,将网格资源发现中的关键功能包装为有状态的Web服务.同时介绍了在该模型中资源加入与离开算法和资源查询算法.该模型结合WEB服务技术、P2P技术与网格资源管理技术的优点,并经试验测试分析与实际项目检验证明该模型能够适应大规模异构环境下的网格资源发现要求.Proposed a new model of grid resource discovery based on WSRF. The model uses three-layer structure as its architecture, and the resources are organized in the method of both centralized and decentralized way. Main functions of gird resource discovery are packed into the stateful web services. Presentd resource membership protocol and resource search algorithm for the model. The advantages of both web service and peer-to-peer architecture are all absorbed into this model. This paper also analyzes the efficiency of the model and proves that it is suitable for large and heterogeneous grid environments.
